PRESS-MOLD FOR MANUFACTURING DUTCH TILES, am.

SPECIFICATION forming part of Letters Patent No. 544,786, dated August 20, 1895.

Application' nea my 14,1894. serai No. 517.605. (no man.)

Eo all whom t may concern:

-Be it known that I, MAXYMILIAN HAROZYK, a subject of the Emperor of Prussia, and a vresident of Warschau, in the Province of Poland, in the Empire of Russia, have invented certain new and useful Improvements in and Relatingto Press-Molds for the Manufacture of Dutch Tiles and other Stove Parts with Flanges, of which the following is an exact specification. v

This invention relates to an improved pressmold for the manufacture of Dutch tiles and other stove parts provided with ianges.

The purpose'of my invention is to manufacture such articles from powdered materials by exposing the latter to pressure in such a manner that the body or tile proper is pressed but once. The flange, however, is pressed twice, all as will be .more fully described hereinafter. t

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the different views, and in which- Figure l is a vertical longitudinal section through the press-mold, taken on line 14. l5 of Fig. 3. Fig. 2 is a vertical cross-section through the same, taken on line 16 17 of Fig. 8. Fig. 3 is a plan ofv the mold. Fig. 4 is a detail of the same. Fig. 'is also a detail drawn on a larger scale. Figs. 6 to 1l represent the various stages occurring in forming a Dutch tile by means of the above pressmold. Figs. l2 and 13 represent two stages occurring it' the several parts of the mold are employed in another order.`

Referring to Figs. 1 to 5, a designates a slide forming thelowest part of the mold and adapted to carry the other parts of the same between the cheeks of a press. is a dat frame resting on slide a and forming with the latter a shallow vessel adapted to receive the material c for the tile proper, Fig. 6.

- d designates a hollow stamp embracing another stamp d and forming with the latter a space d2, adapted to receive the material c' for the ange, Fig. 8. The parts d and d thus form a stamp as well as a mold. Both parts are Iirmly connected by means of a ledge e, Figs. land 2, provided with dovetails and having two cut-outs e e? opening downward directly over the space cl2 aforementioned. Into this space may be lowered a bipartite stamp f f2, Figs. l to 5. Each half of this stamp is cut away at f3 to give room for the ledge e. If, now, frame b, Fig.

6,'has been tilled with the powdered material,

stamp d d is put upon the latter, Fig. 7, and

to take over ledge e if the cheek is lowered or pressed down uponv stamp f f2, respectively, Figs. 1v and 2. Portion c of the mass is thus compressed and turned into a comparatively-solid body-t'. e., the ange of the Dutch tile or other stove `portion just manufactured. (Compare the hatched lines indicating the portions c and vc of the material in Figs. 9 and 10.) Asv soon 'as stamp ff2 has entered the space d2 completely, Fig. l0, the fast connection between the mold or stamp d d and the slide a is broken. Both stamps ff2, as well as d d', are pressed down now simultaneously upon the material contained within frame b, Fig. 1l, so that also this material c is compressed and turned into va coinparatively-solid body-1l. e., the tile proper. It will be observed that also the flange is still furthercompressed during this operation, or, in other Words, is compressed a second-time.

Instead of pressingtheange at lirst and the body of the Dutch tile afterward, I may reverse these operations, as shown in Figs.12

and 13. In this case I proceed as follows: After frame b has been filled stamp cl d is put upon the material and pressed down upon the same, Figl2. Space cl2 is filled then with the material requisite for the flange, Fig. 13,` and the bipartite stampff2 is pressed down as far as possible, Fig. ll, when the whole operation Will be completed.

vHaving thus fully described the `nature of my invention, what I desire to secure by Letters Patent of the United States is- As ameans for manufacturing Dutch tiles and otherV ianged stove-parts, the combination with a press-mold adapted to produce IOO the body or tile proper of the article, of a double stamp consisting of an outer stamp and an inner one, said double-stamp being adapted to form the mold for the flange or flanges of the article, and to receive a'bipartite stamp adapted to be pressed down into the main-stamp independent of the latter, for the purpose as described.

In testimony whereof have signed this specification in the presence ot' two subscrib- 1o ing Witnesses.
